Hello All,
I've run into a problem with getting network performance data on
Windows VMs running on KVM. When I check the network data in the
Windows task manager on the VM, it remains at zero, even if large
amounts of data are being transferred. This has been tested on Windows
Server 2008r2 using the standard Windows driver and the e1000 nic. I
searched the web and the bug reports specifically, but I didn't find
this issue mentioned. Is this expected behavior, or is there something
I can do to fix it?
Below is the info on the hypervisor the VM is running on:
OS: CentOS release 6.4
Kernel: 2.6.32-358.11.1.el6.x86_64
qemu-kvm: 0.12.1.2-3.209.el6.4.x86_64
And the VM details:
